If commercials are what it takes to put such movies on the air, then history is served by whichever sponsors enable the presentation of such films.
I have heard all too many times about anti-Semitic groups who claim it never happened as well as remarks such as "it was a long time ago" that are meant to suggest it could never happen here or again.
Ask a Japanese-American about Manzanar; although there were no ovens, similar discrimination happened here; and not that long ago. Those who do not study history are doomed to repeat it.
